Answer:
2
Step-by-step explanation:
6^2 - 36 ÷ 3^2 x 4 -18
Using BODMAS -Brackets, Of, Division/Multiplication, Addition/Subtraction.
=36 -(36 ÷ 9) x 4 -18
=36 - 4 x 4 -18
=36 -16-18
=2
Following the order of operations as set out in PEMDAS
6² - 36 ÷ 3² × 4 - 18 ( no parenthesis so evaluate exponents )
= 36 - 36 ÷ 9 × 4 - 18 ( multiplication/ division, evaluate from left to right )
= 36 - 4 × 4 - 18
= 36 - 16 - 18
= 20 - 18
= 2
